RUSSO ETALAPPARATUS FOR TREATING FIBERS 2 Sheets-$heet 2 Original Filed Dec. 21,1959 II-lllul'lllllv tates This invention relates to an apparatus forcrimping, packaging and treating textile fibens and has for an object toprovide an apparatus of the above type having novel and improvedcharacteristics.

The nature of the invention will be better understood from the followingdescription, taken in connection with the accompanying drawings in whicha specific embodiment has been shown for purposes of illustration.

In the drawings:

FIG. 1 is a side elevation of an apparatus for unwinding the packagewith parts broken away to show the structure; and

FIG. 2 is a section taken on the line 22 of FIG. 1.

Referring to the drawings more in detail FIGS. 1 and 2 show the package41 as placed on a spindle 70 for unwinding.

A friction washer 71 puts the necessary drag on the package during theunwinding operation. The tape 50 passes from the package 41 through apigtail guide 72 thence over a tension control device 73 which smoothesout the tape for reeling, thence onto a reel 74 driven by a motor 75.

The yarn 76 from the package 41 is fed through guides 77 and 78 thencethrough an eye 79, carried by an arm 80 projecting through a slot 81 ina housing 82 and connected to actuate an arm 84 pivoted at 85 andadapted to actuate a micro-switch 86. The arm 84 carries at its endweights 87 which are adjustable for controlling the tension of the yarn76. The yarn 76 passes from the eye 79 to a fixed guide 88, and to atake-up device such as a constant speed winder having a yarn package 90driven peripherally by a constant speed driving roll 91 where it iswound onto a cone or spool to form a yarn package of the usual type.

The micro-switch 86 is connected to control the operation of the motor75 so as to exert a pull on the tape when the tension on the yarnincreases and to stop the motor 75 when the tension on the yarndecreases. in this way a substantially constant quantity of yarn ismaintained at the discharge point at the bite of the tape on the package41. As more yarn is pulled from the package the discharge point recedesinto the area held compacted by the tape 50 which increases the drag onthe yarn 76. This increased tension closes the microswitch momentarilyand causes the motor to pull the tape and thus turn the package toadvance a further quantity of the core to the discharge point. Thisoperation continues until the entire quantity of yarn has been withdrawnfrom the package and wound onto a cone or other form of package.

This application is a division of lco-pending application Serial No.861,001, filed December 21, 1959, now Patent No. 2,997,747.

What is claimed is:

1. Apparatus for extracting a yarn from a core package in which acontinuous core of crimped fibers is Wound together with a separatingand confining tape in successive convolutions with adjacent convolutionsof said core separated by the interposed tape, comprising an unwindingspindle carrying said package and adapted to turn as the package isunwound, means withdrawing the yarn from said core as the core isexposed at a delivery point, tape feed means connected to withdraw saidtape from said package for thereby exposing said core at the point ofremoval of said tape, drive means for said tape feed means and meansresponsive to variations in tension of said withdrawn yarn to controlthe actuation of said tape feed means for advancing said tape at a rateto maintain said yarn at a substantially constant tension.

2. Apparatus as set forth in claim 1 in which said tape is withdrawn ina path to expose said core substantially at the bite of said tape withsaid winding.

3. Apparatus as set forth in claim 1 in which a mo tor is connected todrive said tape feed means and said tension controlled means is adaptedto energize said motor periodically for advancing said tape at the raterequired to maintain said tension substantially constant.
